Improvement in car-replacers



UNITED STATES PATE T QFrtoa THOMAS B. PURVES, OF GREENBUSH, NEW YORK.

IMPROVEMENT IN CAR-REPLACERS.

Specification forming part of Letters Patent No. 180,062, dated July 18, 1876; application filed March 23, 1876.

To all whom it may concern:

Be it known that I, THOMAS B. PURVES, of

'Greenbush, in the State of New York, have invented a new and useful Improvement in GarReplacers; and that the following is a full, clear, and exact description thereof, reterenee being had to the accompanying drawing making a part of this specification, and to the letters of reference marked thereon.

My invention has for its object the arrangement of the switch-rail of a car-replaoer with a chair to be hooked on and secured to the main rail of a railwaytrack to guide the wheels of a displaced car to their position upon the track.

To this end my invention consists of a chair, one side of which is made to hook over the rail of the track, and the other side having a projecting ear, provided with a hole through which is inserted a key, the lower end of which, when in place, bears against thelower side of the upper part of the rail.

Figure 1 is a perspective view of my inven: tion as applied to a railway-track to guide the wheels ot'a displaced car thereon. Fig. ll is a tmnsverse section of a track-rail, showing the replaeer attached to one side ot'the trackrail; and Fig. III is a similar transverse section, showing the replacer attached to the other side of the track-rail.

In the drawings, A represents the track-rail of a railway, and B represents a chair, one side of which is made in the form of a hook,

the chair is in place upon the traclcrail, the

lower endof the key just extends beneath, and bears against, the upper projecting part of the rail, The switch-rail E is bent at 0, so

that'when in place the part E extends in a horizontal direction, and is pivoted at a to the chair, and the main part of the switch-rail is inclined from the point 0 down to the base of the track-rail at a point, say three feet, more or less, from the chair.

It is obvious that the chair B may be hooked over the rail from either side, and the'switchrail E swung into any desired position to replace a displaced oar.

Having thus described my invention, what I claim as new is The combination of theswitch-rail E, the chair l, provided upon one side with the hook c, and upon the opposite side with the perforated ear 0, and the key D, all constructed and operating substantially as herein described.

, THOS. B. PURVES.
